G. P. Merrill — Minor Constituents of Meteorites. 517 



A 50-gram sample, badly oxidized, submitted to Dr. Whit- 

 field for tests for minor elements, yielded : 



Chromium ._. 0-300$ 



Copper _. 0-016 



Nickel 2-960 



Cobalt 0*090 



Manganese 0-151 



Vanadium trace 



No trace of molybdenum, tungsten, antimony, tin, lead, zinc, 

 gold, silver, or platinum was found. 



(6) Meteoric stone. Selma, Alabama. Described by Mer- 

 rill,* but no analysis given. Examination of thin sections 

 showed the presence of the usual metallic particles together 

 with olivine, enstatite and a monoclinic pyroxene. 



A bulk analysis by Whitfield yielded results as follows, all 

 the iron being considered for the time being as ferric : 



Silica (SiOJ 32-40$ 



Alumina (A1 2 3 ) 4-88 



Iron oxide (Ke 2 3 ) _ 37-00 



Chromic oxide (Cr 2 3 ) 0*19 



Lime (CaO) 1-52 



Magnesia (MgO) 21*05 



Manganous oxide (MnO) 0*27 



Nickel oxide (NiO) 1-88 



Cobalt oxide (CoO) '. . _ . 0-12 



Vanadic oxide (V 2 3 ) _ . _ trace 



99-31 



Considering the metallic portion alone, the results were as 

 follows : 



Total iron 25-866$ 



" chromium ■__ 0-127 



" nickel.. 1-470 



" cobalt... 0-090 



" manganese 0*210 



" vanadium .__ trace 



All the other constituents noted above under 5 were absent. 



(T) Meteoric stone. Ness County, Kansas. Described by 

 II. L. Ward.f No analysis given. The stone was somewhat 

 decomposed through weathering, but yielded approximately 

 15 per cent of nickeliferous iron, which showed :
